Hello.
I have installed latest kernel last week, and since then have the next
problem:
Everytime I do a job involving filesystem access in large amounts (tasks
like cp -R, find, ....) the system becomes to slow, it stops responding
to the keyboard or mouse, and multimedia apps starts becoming to slow
playing music and then it is just a noise what I hear.
Just when the task end, the system comes to a normal state again.
By example:
I have :
root@Voyager:/usr/src/linux/scripts# cd /mnt/home/glozano
root@Voyager:/mnt/home/glozano# du -s
101892 .
root@Voyager:/mnt/home/glozano# cp -R * /home/glozano
then the system comes to slow.... when copy ends everything is normal again.
I booted my system with the 2.4.17 and it does not happen.
